I don't believe php.ini belongs with the rest of the versioned bits as
it's a configuration file.
I think Stefan's proposal of /etc/php5/[version] which mirrors
/usr/php5/[version] makes the most sense. Then the question is whether
or not it makes sense to ship a symbolic link
/usr/php5/[version]/etc -> /etc/php5/[version]
for "compatibility" with other OS distributions.
